I am attempting to use it to transpose my MIDI keyboard realtime into Garageband. I've been able to get the application MIDI Patchbay (
http://notahat.com/midi_patchbay) to transpose the MIDI information from my piano before it gets to Garageband, but I haven't quite figured out how to make it not send the "original" note as well. So basically, I am getting two notes when I press one key; the original
and the transposed one. Is there is a way to "mute" the original note, or "hide" it from Garageband?
